Composition of organic and conventionally produced sunflower seed oil

The aim of the present study was to highlight the
main differences between seed oils produced from conventionally
cultivated crops and organically cultivated ones and
processed using mild extraction procedures. The composition
and the nutritional and health aspects of both types of sunflower
seed oils were compared and were analytically tested to determine
the macroscopic differences in proximate composition,
the main differences in the minor components, the main quality
parameters, the in vitro antioxidant activity, and the presence of
trans-ethylene stereoisomers in FA. No significant trends were
found in the oil samples for TAG and FA composition, but remarkable
differences were found in the composition of minor
components and in the main chemical and analytical quality
properties. The organically grown samples had a higher total
antioxidant activity compared with the conventional samples.
Trans FA were found only in the conventional oils.
